Abstract: Objective: To observe the protective effect of Ghrelin on high glucose-induced hepatocellular injury and preliminarily explore its mechanism. Methods: A high glucose-induced hepatocellular injury model was established and Ghrelin(10-7 mmol / L) was used for intervention. The experiment were randomly divided into blank control group, Ghrelin + blank control group, high glucose group and Ghrelin + high glucose group. The cell proliferation rate and expression levels of alanine aminotransferase(ALT), malondialdehyde(MDA) and superoxide dismutase(SOD) were detected. The mRNA expression levels of cysteinyl aspartate specific proteinase(Caspase-1), interleukin-18(IL-18) and interleukin-1β(IL-1β) were determined by real-time fluorescence quantitative polymerase chain reaction, and the expression of gasdermin D(GSDMD) protein was detected by immunofluorescence technique. Results: Ghrelin could decrease the content of ALT and MDA, increas the SOD content, and significantly reduce the expression levels of pyroptosis-related factors Caspase-1, IL-18, IL-1β mRNA and GSDMD protein. Conclusion: Ghrelin has a protective effect on high glucose-induced hepatocellular injury, and one of its mechanisms may be to relieve oxidative stress and inhibit Caspase-1-mediated pyroptosis.
